Describe the compatibility issue
In-world text (such as nameplates and signs) does not render if the mod Caxton is loaded and a resource pack that adds a Caxton font is enabled.

To Reproduce
Steps to reproduce the behavior:

1. Install Caxton and Iris.
2. Install a resource pack that adds a Caxton font, such as Atkinson Hyperlegible.
3. Activate this shader pack.
4. Look at a nameplate.
5. See error.

Expected behavior
Nameplates and other in-world text is visible.

Screenshots

Desktop (please complete the following information):

• GPU: Intel Iris Xe Graphics
• Shader loader: Iris 1.6.14
• Shader version 1.3.5
• Mod/modpack: Custom modpack

Additional context
Only happens if a resource pack that adds a Caxton font is enabled. If Caxton is loaded without a font it works fine.

Does this issue appear in other shaders?

To add, does the same issue appeared in other shaders pack or no?

I've noticed the same issue occurs with other shaders so it's probably an issue on Caxton's end.

If that is the case, please report this issue to the developers of Caxton instead. I will now close this post.
